PIC16f690 LCD Not Working

[Archangel]

Sorry, I'm wrong, it worked for me too.. in the past, also with 16F690.

I may have a problem with my breadboards. Gonna buy a new one today.

Nevertheless, what I see on my LCD display is on it's first line, a row of blocks, slightly visible.

Of course, I tried to change the contrast, but nothing helps.

I never use a contrast pot, I ground pins 1,3,5,16, put power on 2,15 always works for me. Those breadboards get nasty inside, corrosion after the plating wears a bit, the component pins wear the contacts quickly too.
